To program the ATmega169 using High-voltage (Parallel) Programming, connect the PROGCTRL to PORTD and PROGDATA to PORTB on the STK500 as shown in Figure 2-7.Make sure that the TOSC-switch is placed in the XTAL position. See Section 2.6, “TOSC Switch”.
As described in the STK500 User Guide (jumper settings), mount the BSEL2 jumper in order to High-voltage Program the ATmega devices. This setting also applies to High- voltage Programming of the ATmega169.
The device can now be programmed using the High-voltage Programming mode in AVR
Studio STK500 software.
Note: See the STK500 User Guide for information on how to use the STK500 front- end software in High-voltage Programming mode.
Note: For the High-voltage Programming mode to function correctly, the target voltage must be higher than 4.5V.
Caution: Make sure to disconnect LCD-display from the segment pins header. Other- wise the lifetime of the LCD display may be severely reduced. See Figure 2-10.
